Influence of Donor and Recipient Gender as well as Selected Factors on the Five-Year Survival of Kidney Graft

The aim of the study was to determine the impact of the gender of renal allograft donor and recipient on the graft function over a 5-year follow-up period.Material and methods. The 154 kidney grafts from 77 donors transplanted into recipients of both genders. Two study groups were formed: one group consisted of male donors, while the other consisted of female donors. The recipients in each of the groups consisted of a pair, one male and one female.Results. 71% of grafts survived the five-year period in the group of male and female recipients when the donor was male; in case of female donors, the rate was 62.5%. Depending on the gender of the donor and the recipient, the rates of grafts with five-year survival were as follows: 79.2% for male donors and female recipients (MF); 62.5% for male donors and male recipients (MM). The difference between both groups was not statistically significant. In the case of female donors and male recipients (FM), the five-year survival rate was 58.3%, while in female donors and female recipients, the five-year survival rate was 64.1%.Conclusions. Grafts from male donors show a trend towards better five-year survival compared to grafts from female donors. The highest five-year survival rate was observed when the donor was male and the recipient was female; the lowest rate was observed for female donors and male recipients.
